Trigonometry: Finding the Angle of a Trapezium

The video tutorial explains how to find the size of angle X in a trapezium by splitting it into a triangle and a rectangle. It uses trigonometry, specifically the tangent function, to calculate angle Y in the triangle. The final angle X is determined by adding angle Y to the right angle. The tutorial also discusses the allocation of marks for solving the problem.
